Compatibility with F411RE

Is this compatible with F411RE? I see that the Hello world example uses some conditionals #elif defined(TARGET_LPC1768) to define the EthernetInterface.

Hi Daniel, I also like to know. It couldn't get any Ethernet shield working on this Nucleo board sofar. Regards, Jack.

I had to connect the WIZ SPI pins to the Arduino SPI pins. Like this:

    SPI spi(D11, D12, D13); // mosi, miso, sclk
    EthernetInterface eth(&spi, D10, D7); // spi, cs, reset
    spi.format(8,0); // 8bit, mode 0
    spi.frequency(7000000); // 7MHz

Hi,

Nucleo F411 of ST has also same initialization. I think all nucleo board could use the code of serial and SPI init.

Use it at main:

    Serial pc(USBTX, USBRX);
    pc.baud(115200);
    SPI spi(SPI_MOSI, SPI_MISO, SPI_SCK); // mosi, miso, sclk
    EthernetInterface eth(&spi, PB_6, PA_9);//, nRESET(p9); // reset pin is dummy, don't affect any pin of WIZ550io
    spi.format(8,0); // 8bit, mode 0
    spi.frequency(7000000); // 7MHz
    wait(1); // 1 second for stable state

I found similar one in http://developer.mbed.org/teams/EthernetInterfaceW5500-makers/code/WIZnet_PPPoE/ please refer this. and our collegue have NUCLEO_F401 Board so i ask him to add it. maybe he answer again of his work. 

#elif defined (TARGET_NUCLEO_F030R8)
    Serial pc(USBTX, USBRX);
    pc.baud(115200);
    SPI spi(SPI_MOSI, SPI_MISO, SPI_SCK); // mosi, miso, sclk
    EthernetInterface eth(&spi, PB_6, PA_9);//, nRESET(p9); // reset pin is dummy, don't affect any pin of WIZ550io
    spi.format(8,0); // 8bit, mode 0
    spi.frequency(7000000); // 7MHz
    wait(1); // 1 second for stable state
#elif defined (TARGET_NUCLEO_F334R8)
    Serial pc(USBTX, USBRX);
    pc.baud(115200);
    SPI spi(SPI_MOSI, SPI_MISO, SPI_SCK); // mosi, miso, sclk
    EthernetInterface eth(&spi, PB_6, PA_9);//, nRESET(p9); // reset pin is dummy, don't affect any pin of WIZ550io
    spi.format(8,0); // 8bit, mode 0
    spi.frequency(7000000); // 7MHz
    wait(1); // 1 second for stable state
#endif

Quickly scanning through it I don't see a reason why it shouldn't work. Where did you find the #ifdef part?

In Websocket_Ethernet_HelloWorld_W5500/main.cpp

Those are just example pinouts in the HelloWorld program. In your program replace them with the pins you are using.

Ok, thanks. I wouldn't want to buy the shield only to discover that I can't use it with my F411RE.

posted by Daniel Blendea 10 Feb 2015

I don't have the shield or the F411 myself, so I cannot give you any guarantees, only that I don't see any problems in the code.
